Help!!! engine diagnostic light

[NEWCS1]

My diagnostic light has come on, the car fail its MOT on emmsions. My friend hocked up the a diagnostic computer and told me that i had a miss fire in cylinder one. so i brought my self some new sparkies and ht leads, BUT lol
i cant find out where the ht leads connect ive got a 2001 desire.

i aslo believe that if i was to change the two sensor on the exhaust and give it a full service then maybe it would be ok?
